ThesisItem Open Access Protocol Development of In- Vitro Cultivation of Bamboo ( Dendrocolamus As per )(Birsa Agricultural University, Ranchi, 2002) Peddy Srikanth; Z.A. HaitherBamboos are perennial, woody and evergreen monocotyledonous arborescent grasses belonging to the family Poaceae (Graminae) and Sub-family Bambusoideae. There are about 75 genera and 1250 species of bamboos. Dendrocalamus asper is one of the economically important and widely cultivated bamboo species. The tender shoots of this plant can be consumed as food and is a good source of foreign exchange to various countries. Mature culms of this plant are used for pulp and paper manufacture. Bamboos are propagated artificially by different methods, including through seed. But utilization of seeds as propagating material is difficult and unreliable due to long and unpredictable flowering habit, short dormancy period of seed, poor viability, inborn microbial infestation, poor seed set during off-season flowering, seed sterility and large scale. Consumption of seeds by rodents and wild animals. The vegetative methods, on the other hand, are costly, lobour intensive, cumbersome and time. Consuming. These vegetative propagates are bulky, difficult to transport to distant places and their survival rates are also not very high. This limits large scale cultivation of bamboos in general. Under the situation, propagation through tissue culture seem to be a viable method for large scale propagation of the bamboo species. Therefore the present project was undertaken to establish a protocol for in-vitro propagation of Dendrocalamus asper. In the present study nodal segments (3-4cm) with axillary buds from young juvenile mother plant was used as explants. Surface sterilization using 0.1% (w/v) mercuric chloride (Hgcl₂) for 10 minutes followed by 3-4 times subsequent washing with sterile distilled water proved the best as it resulted the highest percentage (92.68%) of bud break after two weeks. The sterilized nodal segments were cultured aseptically on MS medium supplemented with 0-15 mgl-1 BAP and maximum shoot proliferation. (14-15 shoots per propgule) was achieved on medium supplemented with 12mgl¹ BAP. These proliferated axillary shoots were excised and subcultured on MS liquid medium +3 mgl BAP for the first two subcultures to increase the number of shoots. The shoot multiplication was achieved on both MS solid as well as liquid medium supplemented with 1-5 mgl¹! BAP Highest rate of shoot multiplication (fold) i.e., 15.77 was obtained on MS liquid medium supplemented with 3 mg l-¹ BAP in four weeks. MS solid medium supplemented with 3 mgl¹ BAP resulted only 8.55 fold. Incorporation of NAA (0.2-1.0 mgl ¹) to the medium along with BAP did not increase the rate of shoot multiplication and shoot length but it resulted in better quality erect shoots. MS medium in its full strength (1x) was found to be the most effective basal nutrient medium for shoot multiplication. The studies on sucrose concentration in the medium showed that 3% sucrose was essential for rapid multiplication of shoots. The effect of pH reflected that shoot multiplication occured even on acidic medium and highest rate of shoot multiplication (15.88) was obtained at pH 5.8. A regular subculture cycle at an interval of 4 weeks resulted in healthy cultures devoid of brown leaves and high rate of shoot multiplication. For in-vitro root regeneration on MS medium supplemented with 10mgl-¹ IBA yielded 90% rooting, 19.66 roots per propagule in four weeks, while 3 mg NAA supplemented MS medium resulted 91.66% rooting with 10 roots per propagule NAA resulted short roots while IBA resulted long roots. Addition of BAP (0.1-0.5 mgl ¹) to the rooting medium, neither enhanced root regeneration percentage nor improved the number of the in-vitro roots The cultured plantlets were successfully hardened under high humidity on sterilized soil sand FYM(1:1:1) mixtured with 1/2 strength MS nutrient medium irrigations (without organics).ThesisItem Open Access Protocol Development of invitro Clonal Propagation of Orchid ( Vanda Spa)(Birsa Agricultural University, Ranchi, 2002) Ranjeet Kumar Sinha; Z.A HaitherOrchids, one of the most beautiful group of flowering plants belong to the family Orchidaceae (Monocotyledons). The exquisite beauty of Orchid flowers due to brilliance in colour, remarkable range of sizes, manifold shapes, and variation in the form and wide range of distribution has aroused highest admiration throughout the world. The Orchid comprises about 800 genera with around 35,000 species. In India, about 1300 species of Orchids are found in Himalayas and others scattered in eastern and western Ghats. A vast majority of Indian Orchids are confined to mountain where they are distributed from base of hill to the elevation of 4300 m above mean sea level in climates ranging from tropical to temperate. Orchids are terrestrial, epiphytic, lithophytic or saprophytic but no Orchid is aquatic. The cut flower trade of Orchid involves 3% internationally. Major suppliers, like, Thailand, Netherlands and Singapore export flowers worth of US $ 80.0, 77.4 and 20.0 millions, in order per year. Due to their alkaloid, flavanoid, glycosides and other phytochemical constituents Orchids have high therapeutic value. The flower juice of Vanda coerulea is used to cure eye diseases. Cymbidium elegans, Cymbidium pubescens, Epicactic latifolia are used as local medicines. for treatment of nervous disorders. Orchids are also used in many countries as food or for making refreshing drinks. Unfortunately the natural population of Orchid is fast declining due to excessive collection and over harvesting by traders and botanical explorers. So there is need to cultivate and conserve the endangered Orchids. The conventional method of propagation is tedious and time taking. The alternative means of propagation is in vitro clonal propagation. Keeping this in mind the present experiment. on developing a viable protocol for in-vitro clonal propagation of Orchid (Vanda Miss Joaquim) was undertaken. The explant, like, shoot apex and shoot node were washed with detergent and teepol and then sterilized with 0.2% mercurio chloride for 10 minutes. The explants were cut in small pieces under laminar flow hood and subsequently inoculated in Murashige and Skoog (1962) medium modified with different plant growth regulators. The inoculated materials were cultured under aseptic condition at 25+2°C with 16 hours photoperiod of 3000 lux. The medium containing 2% sucrose, 2 mgl¹ BA+ 0.2 mgl¹ NAA was best for shoot node culture and developed 10 shoots/node and 4 leaves per shoot. Protocorm like bodies were developed in cytokinins combination. The combination 1 mgl BA + 0.3 mgl kinetin proved better for getting higher number of buds. However, 7.67 buds/node were found with 1mgl kinetin + 0.1 mgl¹ 2,4-D in around 46 days. It is worthy to note here that 2 mg1¹ kinetin in absence of 2,4-D yielded 7.56 buds/node which is statistically at par with the combination treatment 1mgl kinetin + 0.1 mgl 2,4-D. The shoot apex culture gave significant results on MS. medium supplemented with 2 mgl¹ BA + 0.5 mgl'¹ NAA, 1 mgl¹ BA + 0.2mgl kinetin and 1mgl kinetin + 0.1 mgl 2,4-D. Sub-culturing of plantlet on 2 mgl¹ BA and 0.5 mgl¹ NAA gave about 70-100 shoots. Best result on rooting was achieved on MS medium supplemented with 1 mgr¹ IBA+ 0.5 mgl¹ NAA, 1 mgr¹ NAA + 0.1mgl¹ BA. The maximum root length (49.5 mm and 60 mm) was obtained on medium supplemented with 1 mgr¹ NAA+ 0.1mgr¹ BA and 2 mgl¹¹ NAA + 1 mg/¹¹ IBA respectively. The cultured shoots were hardened successfully in pots containing bark, brick pieces and charcoal in 1:1:1 ratio.ThesisItem Open Access Effect of Pre-Sowing Seed Soaking On Rice Productivity under Upland (Rainfed) Condition(Birsa Agricultural University, Ranchi, 2002) Manoj Kumar; A.K.VermaRice ( oryza staviya) I sone of the popular staple food crop in.

RafeyStudies on nutrient management of Urdbean (vigna mungo L. Hepper) under late sown condition was conducted during rainy (Kharif) season of 2000 in ultipaleustalf red loam soil (Belonging to the Red- Yellow - Light grey catenary soil association group representing major soil group of plateau region) of Birsa Agricultural University farm, Kanke, Ranchi. The soil reaction was slightly acidic (pH 6.8). The experiment was laid out in factorial randomized block design with three replications. Twelve treatments in combination with four nitrogen levels management (20 kg N/ha as basal, 20 kg N/ha as basal + 10 kg N/ha as foliar, 30 kg N/ha as basal+ 10 kg N/ha as foliar and 30 kg N/ha as basal) and three population densities (5 lakh plants/ha, 4 lakh plants/ha and 3.33 lakh plants/ha maintained at spacing 20x10, 25x10 and 30x10 cm, respectively) were studied for the production of Urdbean. The recommended doze of 40 kg P₂Os and 20 kg K₂0/ha was applied as basal in furrow at the time of sowing in the form of single super phosphate and muriate of potash, respectively. On the basis of one year of experimentation it was revealed that the urdbean crop sown under late sown condition was influenced by nitrogen levels and population densities. Higher grain yield (11.8 q/ha), straw yield (47.6 q/ha), harvest index (19.91 %), net return (9761.5 Rs/ha) and benefit cost ratio (1.96) was obtained when 30 kg N/ha was applied as basal and sowing was done at 25x10 cm spacing (4 lakh plants/ha) and found to be significantly superior among all the nitrogen levels and population densities. Urdbean roots and nodules were also significantly influenced by nitrogen levels and population densities. Higher lateral (8.7 cm) and vertical (19.0 cm) expansion of roots, dry weight of roots (0.50 g), number of nodules (47.0), effective nodules (42.0), per cent effective nodules (89.3) and dry weight of nodules (0.29 g) per plant was recorded when 30 kg N/ha was applied as basal and sowing was done on 25x10 cm spacing (4 lakh plants/ha). But the Nitrogen concentration in nodules was higher when 30 kg N/ha was applied as basal + 10 kg N/ha as foliar and sowing was done on 25 x 10 cm spacing. Nitrogen, phosphorus and potassium concentration in grain and straw of urdbean was higher when 30 kg N/ha as basal + 10 kg N/ha as foliar was applied and crop was sown on 25 x 10 cm spacing (4 lakh plants/ha). Nitrogen, phosphorus and potassium uptake in grain and straw of urdbean crop and its total uptake was higher when nutrient was applied @ 30 kg N/ha as basal and crop was sown at spacing 25 x 10 cm (4 lakh plants/ha) and found to be significantly superior among all the nitrogen levels and population densities. Value of available nitrogen, phosphorus and exchangeable potassium of soil after urdbean harvest was higher when nutrient was applied @ 30 kg N/ha as basal + 10 kg N/ha as foliar at 25 x 10 cm (4 lakh plants/ha) spacing. Net change in soil fertility after harvest of Urdbean crop was also significantly influenced by nutrient management and population densities. Higher value of nitrogen, phosphorus and potassium was recorded when crop was sown at 25 x 10 cm spacing (4 lakh plants/ha) with the nutrient application of 30 kg N/ha as basal + 10 kg N/ha as foliar.ThesisItem Open Access Host Genotype X Rhizohium Interaction in Vigna Species(Birsa Agricultural University, Ranchi, 2002) Praveen Singh; M.

Merge attention has been paid to nitrogen level in isolation which is also an important aspect of intercropping system as the component crops arc are different in nature of growth and nitrogen needs. Therefore this study was carried out on the effect of nitrogen levels on mustard + chickpea intercropping system during the rabi (winter) season of 1998-99 on a rainfed upland sandy loam soil of Birsa Agricultural University Farm, Ranchi. The experiment was laid in Split Plot Design in intercropping of mustard + chickpea with two ratio (1:1 and 2:1 row ratio) which constituted main plot and three levels of nitrogen (control (no fertilizer), 20 kg nitrogen and 40 kg nitrogen per hectare). A uniform dose of phosphoric @ 40 kg POs ha in the form of SSP and K,O 20 kg ha¹ as muriate of potash was applied at the time of sowing. In addition to intercropping two sole crops of mustard and chickpea were allocated randomly in each replication for comparison. Salient features of the results of the experiment are given below. The assessment of the row ratio and yield advantages revealed that through the yield attributes, yield per se of component crops in intercropping system were reduced as compared to those of the sole crops, the combined equivalent yield of component crop in intercropping system exceeded the higher sole crop yield. The periodic plant height of mustard was not influenced by intercropping system, the maximum height (127 cm) of mustard was recorded at harvest, while the levels of nitrogen greatly influenced the height of mustard plants. The maximum height of mustard was obtained with the application of 40, kg per hectare N which was significantly more than that obtained with other treatments. Similar results were also obtained at 60 and 75 days after sowing. Yield components (primary and secondary branches, seeds/siliquae pod, siliquae or pod per plant and 1000-seed weight) were influenced by intercropping and level of nitrogen. The yield of the component corps, in intercropping systems, reduced as compared to those of the sole crops. The combined equivalent yield of component crop in intercropping system exceeded the sole crop yield. The intercropping system (mustard + chickpea 1:1) was the best from yield (equivalent yield 1776 kg/ha), Economic return (Rs.22,095/ha) and bio-energetic (Energy use efficiency by grain 3.02) point of view. Application of 40 kg nitrogen per hectare gave maximum equivalent yield (1850 kg/ha), economic return (Rs.23,173/ha) and bio-energetic (Energy use efficiency by grain 2.79). Although sole chickpea produced the highest net return (Rs.33,180/ha) and benefit: cost ratio (5.99). Sole chickpea left more available nitrogen in soil as compared to that recorded in intercropping system, which was followed by the intercropping of mustard + chickpea (1:1 row ratio). Under different nitrogen levels, application of 40 kg nitrogen left more available nitrogen than any other treatments. There was no effect on availability of phosphorus, potassium and organic carbon. Moreover, the availability of potassium and phosphorus was maximum in control plots. The experimental results and economic analysis of the experiment indicated that sale crop of chickpea in upland rainfed situation of plateau region of Jharkhand showed best performance. Among the intercropping systems, mustard + chickpea (2:1 row ratio) can profitably be replaced by mustard + chickpea (1:1 row ratio) intercropping system. The application of 40 kg nitrogen gave the maximum net return which was at par with the application of 20 kg nitrogen per hectare.ThesisItem Open Access Production Potential of Finger Millet Cultivars under Different Nitrogen Levels In Rainfed Condition(Birsa Agricultural University, Ranchi, 2001) Md.Naiyar Ali; S.AhmedA field experiment was carried out to study the production potential of finger millet cultivars under different nitrogen levels in rainfed condition" during kharif 2000 at Birsa Agricultural University Farm, Ranchi. The experiment was laid out in Randomized Block Design with three replications. Treatment consisted of six finger millet cultivars (A404, PR202, HR374, BM2, JBT2 and BAU2) with three nitrogen levels (20, 40 and 60 kg N ha¹). The experimental soil was representative sandy loam in texture and acidic in reaction with low in organic carbon, available nitrogen, medium in available phosphorus and potassium. Among finger millet cultivars A404 and PR202 (long) duration) performed better growth, higher number of tillers plant and metre row length, higher gain weight ear and test weight, maximum mean grain yield (17.03 q ha¹) and net return (Rs.4428.2 ha¹) with higher benefit cost ratio (0.84) in comparison to cultivar HR374 and BM2 (medium) and JBT2 and BAU2 (short duration). Grain yield of long duration cultivars was increased by 9.4 and 17.7% as compared to medium and short duration, respectively. Application of 60 kg N ha ha' produced taller plant, higher yield attributes (tillers plant', grains ear¹ and test weight) maximum grain yield (18.90, q ha¹) and net return (Rs.4720, ha¹) with higher benefit: cost ratio (0.83) which was closer to 40 kg N ha".ThesisItem Open Access Histological And Certain Histochimical Studies on Oviduct of Domestic Hen ( Gallus Domesticus )(Birsa Agricultural University, Ranchi, 2002) Suresh Mehta; P.N.

The mucosal folds were leaf like in developing birds whereas they were slightly wider and finger like in laying birds. The mucosal glands were absent in vagina. The epithelium of vagina in developing birds showed moderate to strong affinity for PAS and bromphenol blue stain and moderate for alcian blue and colloidal iron. On an average lamina epithelial is of laying birds had more affinity for PAS +ve substance and bromphenol blue but had weaker affinity for alcian blue.ThesisItem Open Access Evaluation of The Fentanyl And Its Combination With Droperiodol And Haloperidel For Epidural Analgesia -in Dogs(Birsa Agricultural University, Ranchi, 2001) Sanjay Kumar; L.L. DasHypothermia was a consistent feature of narcotic analgesic (fentanyl) and neuroleptanalgesic, however, decreasing trend in body temperature was marginal and short lived. Bradycardia and bradypnoea are the regular features of neuroleptanalgesia however, these are preceded by an appreciable increase in heart and pulse rate. Epidural administration of fentanyl @ 0.01 mg/kg induced optimal sedation but intense analgesia and relaxation could be observed for 30 minutes. muscle Sedation, analgesia and muscle relaxation were variant in two combinations. Fentanyl + droperidol produced excellent sedation and analgesia with optimum muscle relaxation for nearly 1 hour, while fentanyl + haloperidol produced satisfactory analgesia and sedation for about 70 minutes. The combination of fentanyl with droperidol and haloperidol evinced abolition of superficial and deep cutaneous reflexes over a wider region of body, permitting surgery of different magnitude, than fentanyl alone.. In terms of duration of effect and magnitude of muscle relaxation, combination seemed to be superior. It is suggested that surgery under stress condition may be performed of fentanyl and its combination with droperidolo/haloperidol. Aspartate transaminase, blood urea nitrogen and creatinine levels exhibited non-significant alterations within normal physiological limits and suggested non-toxic effect of the anaesthetic regimens on liver, kidney, muscles and heart. The increasing trend of glucose observed in all groups was transitory and marginal and hence neuroleptanalgesia can be safely employed in both hyper- and hypoglycaemic patients.
